Alkalescent diatom ooze wall material and preparation method thereof

Abstract

The invention discloses an alkalescent diatom ooze wall material and a preparation method thereof. The wall material comprises, by weight, 300 parts to 600 parts of diatom ooze of 200 meshes to 400 meshes, 200 parts to 500 parts of silica flour of 100 meshes to 200 meshes, 100 parts to 400 parts of wollastonite powder of 200 meshes to 400 meshes, 100 parts to 400 parts of bentonite of 200 meshes to 400 meshes, 200 parts to 500 parts of objective palygorskite of 200 meshes to 400 meshes, 20 parts to 50 parts of plant cellulose and 10 parts to 40 parts of nano polymers. The alkalescent diatom ooze wall material has weak alkalescent corrosion and a porous optical channel structure, the specific gravity of the material is smaller than that of water, the material is easy to suspend on the water surface, rays can be refracted inside the wall material, and the ray utilization rate is high. The invention further provides a preparation method of the alkalescent diatom ooze wall material, as the wallmaterial is alkalescent, and the stirring and blending is easy, the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of building and household materials, in particular to a weakly alkaline diatom mud wall material and a preparation method for the weakly alkaline diatom mud wall material. Background technique [0002] As we all know, the construction of the wall is particularly important after the completion of the rough home furnishing in the field of construction and home furnishing, so that there is a choice of wall materials. "Wall material", as the name implies, refers to the material related to the wall painting construction and the ordinary mortar surface. Nowadays, people not only have to face possible pollution in public places, but also have to face pollution from private individuals and even the human body itself. Therefore, in an era when various cancer symptoms are increasing, the "green revolution" has become an inevitable choice to ensure ecological balance and ecological stability. However, some of the cur...

Problems solved by technology

[0004] The current several wall materials for absorbing and purifying harmful substances in the air mainly have the following disadvantages: 1. Most of them add materials such as cement and ash calcium powder. The chemical composition of cement is tricalcium silicate (3CaO·SiO2, simplified C3S ), dicalcium silicate (2CaO·SiO2, simplified formula C2S), tricalcium aluminate (3CaO·Al2O3, simplified formula C3A), tetracalcium aluminoferrite (4CaO·Al2O3·Fe2O3, simplified formula C4AF)

These chemical components cause the wall material to be strongly alkaline, so it is highly corrosive, causing inconvenience in construction, and the wall is blooming after construction.

2. The reaction of materials such as cement, ash calcium powder and diatom mud is easy to block the breathing pores, resulting in a large proportion of the material, which is not easy to suspend on the water surface, resulting in uneven mixing and easy layering of the material.

3. Because the cement, ash calcium powder and the material react to block the gaps in the weakly alkaline diatom mud wall material, the light cannot be transmitted to the inside of the material and only exists on the surface, so that the catalytic reaction only occurs on the surface layer, which greatly reduces the wall material. Utilization rate, resulting in unsatisfactory adsorption and air purification effect

4. Simply using nano-titanium dioxide as a catalytic material does not have a high utilization rate of light

5. Due to the strong alkalinity and easy layering of the material, professional and technical personnel are required for construction, which reduces the operability of the material
